Child Swallowed Mercury: Immediate Steps and Medical Guidance

Emergency Response for Mercury Ingestion

Mercury is a potent neurotoxin. Even small amounts can cause kidney and brain damage, especially in children. Act immediately.

Immediate Actions

1. Call Poison Control: 1-800-222-1222 (U.S.) – Available 24/7. They provide real-time, case-specific instructions.
2. Do NOT Induce Vomiting: Aspiration risk; mercury vapor inhalation damages lungs.
3. If Conscious & Swallowing: Give milk or water to dilute (per Poison Control guidance).
4. Go to ER Immediately: Bring the mercury source (thermometer, bulb, etc.) if possible.

Medical Evaluation Includes

• Airway/breathing assessment.
• Blood/urine mercury levels.
• Imaging (X-ray) to locate elemental mercury (radiopaque).
• Chelation therapy consideration (e.g., succimer) for significant exposure.
• Neurological and renal monitoring.

Sources of Exposure

• Broken fever thermometers (elemental mercury).
• Button batteries (some contain mercury oxide).
• Fluorescent bulbs, old switches, cultural/folk remedies.

Prevention

• Use digital thermometers only.
• Secure button batteries.
• Recycle bulbs/batteries properly.
• Educate caregivers.

Time is critical. Early intervention dramatically improves outcomes.
